FRAGILE WATERMARKING FOR IMAGE AUTHENTICATION USING DYADIC WALSH ORDERING


Space-Time Water-Filling for Composite MIMO Fading Channels

We analyze the ergodic capacity and channel outage probability for a composite MIMO channel model, which includes both fast fading and shadowing effects.The ergodic capacity and exact channel outage probability with space-time water-filling can be evaluated through numerical integrations, which can be further simplified by using approximated empiri

atonal- and achaete-scute-related genes in the annelid Platynereis dumerilii: insights into the evolution of neural basic-Helix-Loop-Helix genes

Abstract Background Functional studies in model organisms, such as vertebrates and Drosophila, have shown that basic Helix-loop-Helix (bHLH) proteins have important roles in different steps of neurogenesis, from the acquisition of neural fate to the differentiation into specific shibori dot fabric neural cell types.However, these studies highlighte

A Universal LiDAR SLAM Accelerator System on Low-Cost FPGA

LiDAR (Light Detection and Ranging) SLAM (Simultaneous Localization and Mapping) serves as a basis for indoor cleaning, navigation, and many other useful applications in both industry and household.From a series of LiDAR scans, it constructs an accurate, globally consistent model of the environment and estimates a robot position inside it.SLAM herb

Formation of the honeycomb-like MgO/Mg(OH)2 structures with controlled shape and size of holes by molten salt electrolysis

Synthesis of the honeycomb-like MgO/Mg(OH)2 structures, with controlled shape and size of holes, by the electrolysis from magnesium nitrate hexahydrate melt onto glassy carbon is presented.The honeycomb-like structures were made up of holes, formed from detached hydrogen bubbles, surrounded by walls, built up of thin intertwined needles.For the fir
